Twice Health
https://www.nexusmods.com/terminatordarkfatedefiance/mods/6

Everything have twice health. That's it.
Your units, enemy units, buildings, everything.
Make your battles less dependent on RNG.
It could also make battles much easier, while rather intense.
Realistic difficulty is recommended here.

New campaign is recommended.

Nice you were able to adress the supply consumption! In my attempts to prolong battles by decreasing the damage to both player and enemies I faced real ammo problems.

But it's nice that units aren't disabled after a first (un)lucky hit. Definately recommend using those mods - as the battle orchestration is way too beatiful to be over as fast as in the vanilla game.

Yep. Ammo could be a more of a problem with Twice Health. ;)

Not deeply tested that yet, but for a several mission in is OK.

Mixed up files for these 2 mods.
"Harder Difficulty" files were for "Twice Health" and "Twice Health" files was for "Harder Difficulty".
Fixed. :P

Playing on Relistic with Twice health and it is fun!
Very intense. But quite taxing on PC as enemy don't die as soon you see them.
